Insert new liner. Push liner against quick-connect plug and tighten setscrew(s). Cut liner off so that 7/16 in (11 mm) ± 1/32 in (.8 mm) sticks out of head tube. Install adapter, contact tip, insulator, and nozzle. Lay gun cable out straight before installing new liner. Head Tube 7/16 in Remove liner. Remove nozzle, contact tip, and adapter. Blow out gun casing. Disconnect gun from unit. Tools Needed: Loosen setscrew in quick-connect plug. It may also be necessary to loosen setscrew in adapter. Quick-connect Plug 1/16 in Nozzle Contact Tip Insulator Adapter Ref. ST-802 290 OM-192 440 Page 20 4-6. Welding Troubleshooting Table Welding Trouble Remedy No weld output; wire does not feed. Secure power cord plug in receptacle (see Section 2-11). Check and replace power switch if necessary. Check circuit breakers CB1 and/or CB2, and reset if necessary (see Section 4-2). Replace building line fuse or reset circuit breaker if open (see Section 2-11). Secure gun trigger leads in receptacle or repair leads, or replace trigger switch (see Sections 2-4 and/or Parts List). Thermostat open (overheating). Allow fan to run; the thermostat will close when the unit has cooled (see Section 2-2). No weld output; wire feeds. Connect work clamp to get good metal to metal contact. Replace contact tip (see Section 4-4). Low weld output. Connect unit to proper input voltage or check for low line voltage (see Section 2-11). Low, high, or erratic wire speed. Readjust front panel settings (see Section 3-1). Change to correct size drive roll (see Section 4-3). Readjust drive roll pressure (see Section 2-12). Replace inlet guide, contact tip, and/or liner if necessary (see Sections 4-3, 4-4 and/or 4-5). 4-7. Wire Drive/Gun Troubleshooting Table Wire Drive/Gun Trouble Remedy Electrode wire feeding stops during welding. Straighten gun cable and/or replace damaged parts (see Section 4-5). Adjust drive roll pressure (see Section 2-12). Readjust hub tension (see Section 2-8). Check circuit breakers CB1 and/or CB2, and reset if necessary (see Section 4-2). Replace contact tip if blocked (see Section 4-4). Clean or replace wire inlet guide or liner if dirty or plugged (see Sections 4-3 and/or 4-5). Replace drive roll if worn or slipping (see Section 4-3). Secure gun trigger leads in receptacle or repair leads, or replace trigger switch (see Section 2-4 and/or see Parts List). Check and clear any restrictions at drive assembly and liner (see Section 4-5). Have nearest Factory Authorized Service Agent check drive motor.
